Isolation and characterization of the Rickettsia prowazekii recA gene [PDF]
Journal of Bacteriology, 1994 The recA gene has been isolated from Rickettsia prowazekii, an obligate intracellular bacterium. Comparison of the amino acid sequence of R. prowazekii RecA with that of Escherichia coli RecA revealed that 62% of the residues were identical. The highest identity was found with RecA of Legionella pneumophila, in which 69% of the residues were identical.

Phylogenetic Diversity of NTT Nucleotide Transport Proteins in Free-Living and Parasitic Bacteria and Eukaryotes [PDF]
, 2017 Plasma membrane-located nucleotide transport proteins (NTTs) underpin the lifestyle of important obligate intracellular bacterial and eukaryotic pathogens by importing energy and nucleotides from infected host cells that the pathogens can no longer make ...

Use of Deep Sequencing to Evaluate Transitions in Microbial Communities in Stranded Sargassum
International Journal of Microbiology, Volume 2025, Issue 1, 2025.Deep sequencing technologies can be used to evaluate pathogens in environmental samples. The objective of this study was to use this technology to evaluate Sargassum samples that were characterized by different stranding times, one classified as short‐term stranded (STS) and another classified as long‐term stranded (LTS) Sargassum.

Hemocytes from Pediculus humanus humanus are hosts for human bacterial pathogens.
Frontiers in Cellular and Infection Microbiology, 2015 Pediculus humanus humanus is an human ectoparasite which represents a serious public health threat because it is vector for pathogenic bacteria. It is important to understand and identify where bacteria reside in human body lice to define new strategies ...

Reassessment of the genetic basis of natural rifampin resistance in the genus Rickettsia
MicrobiologyOpen, Volume 13, Issue 4, August 2024.Contrary to previous studies, the natural resistance of Rickettsia, a genus of intracellular bacteria, to the antibiotic rifampin is not solely due to the Leu‐973 residue in the RNA polymerase β subunit. Abstract Rickettsia, a genus of obligate intracellular bacteria, includes species that cause significant human diseases.

Changes in Aphid Host Plant Diet Influence the Small-RNA Expression Profiles of Its Obligate Nutritional Symbiont, Buchnera. [PDF]
, 2019 Plants are a difficult food resource to use, and herbivorous insects have evolved a variety of mechanisms that allow them to fully exploit this poor nutritional resource. One such mechanism is the maintenance of bacterial symbionts that aid in host plant
